How do you take out valency an element?
Group number 1 = Valency 1+group number 2 = valency 2+group number 3 = valency 3+group number 4 = valency 4+ and 4- (some cases) group number 5 = valency 3-group number 6 = valency 2-group number 7 = valency 1-group number 8 = valency 0For the transition elements they will either state Copper (III) Sulphate or it will be like Cu2(SO4)3You can find the valency by the base of sulphate and you know its positive because metals are always positive and are written in the left.Source: I am a GCE O Level Sciences Student (O2)
